JOI-IN U. FIESTER, OF WINCHESTER, OHIO.

CI-IURN.

Specification of Letters Patent No. 14,309, dated February 26, 1856.

To all whom t may concern:

Be it known that I, J OI-IN U. FIESTER, of Winchester, 'in the county ofGuernsey and State of Ohio, have invented a new and useful Improvementin Churns; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings and to the letters of reference marked thereon.

Figure l is a perspective view of the churn with two sides and coverremoved to show the interior of the same. Fig. 2, is a perspective Viewof the dasher.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I construct my churn of any of the ordinary materials used for suchpurposes.

In Fig. l letter A, the bottom; B, the frame; C, the sides; D, a portionof the top, the other portion having been removed; E, the crank; F, theupright to steady the crank shaft, G journal for the crank shaft to playin. II journal for dasher, or agitator. J agitator, a holes in theagitator, b cams, 0 spindle of agitator, CZ journal in which it runs, ethe eccentric.

In the operation of my invention, motion is given to the agitator by anypower applied to the crank, which causes the agitator J to revolve, andas it revolves on its own aXis as seen at journal Z it is eccentric tothe eccentric circle e, and as the cams operate alternately on theeccentric e thus giving to the agitator a double lateral motion turn ineach revolution of the agitator. The agitator is composed of threepieces, two of which are hung on a pin to the center piece, and areprevented from getting out of their proper position by means of theeccentric circle e and the cams There are holes a of any desirablenumber in the agitator, and as those adjustable sides are made tooperate laterally these holes are constantly changing their capacity toreceive, and check the iiow of the cream through them, thus causing acontinual action, and reaction on the cream, by abruptly checking andallowing the flow of the current of the cream through the holes. Bymeans of the cams b operating on the eccentric circle e a rubbing motionis given to the agitator, by which a constant friction is kept up uponthe cream forced between the agitators for the purpose of more speedilydisconnecting the but- .ter from the milk, or the globules in which itis contained.

Having thus fully described the construction and operation of myimprovement what I claim as new and desire to secure by Letters Patent,is:

The cams Z) and eccentric circle e in combination wit-h the agitatorsfor the purpose of breaking or cutting the current of cream in itspassage through them and for producing friction by the lateral motion ofthe two sides of the agitator as herein described, and for the purposesset forth.

JOHN U. FIESTER.
